Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof floor structure at the entrance and exit of an assembled bathroom unit (including a shower unit).

[0002]

2. Description of the Related Art Generally, fittings such as hinged doors, folding doors and sliding doors are installed at entrances and exits of a bathroom unit which is an assembly type sanitary equipment room. These fittings consist of a fitting frame part and a shoji part. In general, both the fitting frame and the shoji part are made of extruded aluminum and plastic, and the fitting frame consists of two left and right vertical frames and an upper frame. , 4 in the bottom frame
The four extruded materials are assembled with screws and the like to form a four-sided fitting frame. The fitting frame is stacked on the wall loading surface on the outer peripheral portion of the waterproof floor similarly to the wall panel which is the structure of the bathroom unit, and becomes a part of the structure of the bathroom unit. The shoji part is
It is movably attached to this fitting frame and opens and closes to become an entrance.

The above-mentioned fitting frame is mounted and mounted on a waterproof floor in substantially the same state as a wall panel constituting a bathroom unit.
Similar to the wall panel, it is required to have watertightness so that water does not leak from the connection portion to the outside of the bathroom unit. In addition, not only the fittings, but also the water leaks from the wall panel connection that constitutes the bathroom unit. The raised side is formed so that it does not easily leak water to the outside.

[0004]

However, as described above, a normal fitting frame is constructed by assembling four long extruded members of an upper frame, a vertical frame, and a lower frame with screws or the like.
Since the connection portions are configured as square frames, a gap is easily formed in each connection portion, and it is difficult to obtain sufficient watertightness. Naturally, in order to enhance the watertightness of this part, it is considered that the connecting part is assembled while sandwiching a watertight material, but each frame material is generally made of extruded aluminum or plastic. The wall thickness is small (about 1-2 mm), and the connection method is a simple butt connection. However, the structure was such that only a little inferior watertight performance was obtained. In particular, the joints between the lower frame and the left and right vertical frames are subject to severe conditions because they are easily exposed to water.In addition, with products for elderly people in recent years, the entrance step of the fittings is small, and it blocks the water in the bathroom. Since the specifications mainly do not have a drainage groove with a grating, the water used in the bathroom easily reaches the lower frame of the fitting, and the environment of the lower frame of the fitting is watertight.

[0005] In order to reinforce the weak points of the fitting frame fitting surface, there is a means for improving the watertightness by using another piece for connecting each frame material at the connecting portion, but the fitting is special, and the cost is reduced. Is not so commonly used.

In a normal bathroom unit, even if water leaks from a connecting part such as a fitting part or a wall panel constituting a room as described above, even if water leaks,
(Usually 20mm to 40mm outside from the wall of the bathroom unit)
The worst case of leaking water to the outside was prevented,
In the current mainstay product specification for the elderly, the water-return side of the fitting floor needs to be removed from the final water-return side of the fittings due to the joint dimensions. If there was water leakage, even a small amount of water would directly lead to external water leakage. this is,
If an attempt is made to reduce the entrance step with a product for the elderly or the like, the last water return side of the waterproof pan interferes with the lower frame of the fitting.

[0007] Further, since the wall loading surface of the waterproof floor communicates with the entire circumference of the floor, the removal of the last water return side of the fitting installation portion means that the final water is not placed on the outer periphery of the waterproof floor other than the fitting installation portion. No matter how high you raise the backside, it will eventually only function as a water return to the level of the removed fitting installation part, not only direct water leakage from the lower part of the fitting, Regardless of the leaking water from any part, as for the leaking water that has reached the back of the wall, there is a problem that the watertight performance is significantly reduced if the final water return side is cut in any part.

As a solution to this problem, there is a means of forming a waterproof floor shape so as to cover the entire lower frame of the fitting so as not to interfere with the fitting without removing the water return. The expected size of the lower frame is generally 70mm-10
Because it is about 0 mm, which is much larger than the expected size required for the wall panel, if you try to cover all places where fittings may be installed with a waterproof floor, the waterproof floor will be one size larger And it will not fit in the predetermined bathroom unit installation location.

Further, if the waterproof floor is extended and protruded only at the position where the fittings are attached to form a shape that covers the lower frame, several types of expensive waterproof floors are required according to the position of the fittings, that is, the entrance itself. Which is very inefficient.

[0010] In view of the above, the present invention has been made in view of the above circumstances, and even when water leaks from the fitting frame and other wall panel joints to the back of the fitting frame and the back of the wall, the water leaking from that portion is reduced to external leakage. An object of the present invention is to provide an inexpensive floor entry / exit floor structure of a bathroom unit that is less likely to be watertight and has improved watertight safety.

[0011]

According to a first aspect of the present invention, there is provided a waterproof floor having a wall panel loading surface on an outer peripheral portion thereof, the outer peripheral portion of the waterproof floor being further outside the loading surface. Hold the water-returning edge raised upward, and install the lower part of the fittings by protruding from the outer periphery of the waterproof floor to the dressing room side, or delete the water-returning edge of the fittings installation part of the waterproof floor. In the bathroom unit installed on the wall loading surface, a waterproof tray separate from the floor body is provided on the back side of the lower frame portion of the fitting.

According to the present invention, even in the event that water leaks from the joint of the frame of the lower frame of the fitting, the leaking water is caught by the waterproof tray provided on the lower surface of the lower portion of the lower frame so that the water does not leak to the external building frame. be able to.

According to a second aspect of the present invention, in the case of the first aspect of the present invention, the waterproof tray rises upward above a wall loading surface of an outer peripheral portion of the waterproof floor and an outer periphery of the wall loading surface. It is characterized by being connected in a watertight manner to the final water return side.

According to the present invention, since the waterproof tray is water-tightly connected to the waterproof floor main body, it is possible to make it difficult for the water that has flowed to the rear surface of the wall to leak to the outside even if water leaks from any part.

According to a third aspect of the present invention, in the case of the first and second aspects of the present invention, the side of the waterproof tray facing the dressing room side is near a portion connecting the fitting lower frame and the dressing room side. The upper edge of the rising edge is folded back in parallel with the dressing room floor finishing surface, and when connecting the fitting lower frame and the dressing room floor, the space between the fitting lower frame mounting flange and the dressing room floor surface It is characterized in that it is sandwiched between and attached.

According to the present invention, the upper edge of the side facing the dressing room side of the waterproof tray is connected to the dressing room floor, so that the mounting strength can be increased. And the upper edge of the waterproof tray can be raised near the level of the dressing room finishing surface, thus restoring the last water return side of the waterproof floor cut out to install the fitting frame. High water tightness can be guaranteed up to the top.

The invention according to claim 4 of the present invention is characterized in that the waterproof tray is formed of a thin material having a thickness of 2 mm or less.

According to the present invention, the waterproof tray can be installed without greatly affecting the fitting dimension between the fitting lower frame and the waterproof floor.

According to a fifth aspect of the present invention, a waterproof floor mounting end of the waterproof tray has a folded side folded downward, and is provided on a waterproof floor wall mounting surface to which the waterproof tray can be attached. Is formed with a concave groove, inserts the folded side of the waterproof tray into the groove, and inserts a holding piece having a soft material from above into the groove of the waterproof floor,
The waterproof tray is fixed and attached by being fitted to the floor.

According to the present invention, when the waterproof tray is connected to the waterproof floor, the waterproof tray can be easily mounted with high watertightness without unnecessarily increasing the strength of the waterproof tray.

[0021]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an entrance / exit floor waterproof structure of a bathroom unit according to an embodiment of the present invention.

As shown in FIG. 1, the bathroom unit Y is provided adjacent to the undressing room D, and an entrance 1 leading to the undressing room D is formed on the washing unit 23 side of the bathroom unit Y. . The bathroom unit Y is an assembling type unit bathroom. A wall loading surface 21 for mounting the wall panel 3 is formed on an outer edge of the waterproof floor 2 integrally formed of a resin material. I have. On the outer periphery of the wall loading surface 21, there is a final water return side 20 rising upward.
Is formed, and the wall panel 3 is placed on the wall loading surface 21 at the outer edge of the waterproof floor 2, and the fitting frame 4 is placed on the wall loading surface 21 at the entrance 1 in the same manner as the wall panel 3. You.

A ceiling panel (not shown) is mounted and fixed on the upper part of the wall panel 3 to form a bathroom unit structure. In this case, the wall loading surface 21 is formed at a position lower than the washing scene 23 of the waterproof floor 2, and the wall loading surface 2
A groove 22 having a concave shape is formed substantially in the center of the groove 1 along the longitudinal direction.

The entrance 1 comprises a fitting frame 4 and a shoji (shoji) 40 which can be opened and closed. As shown in FIG. 4, the fitting frame 4 comprises four vertical frames 41 on the left and right and an upper frame (not shown) and a lower frame 42 on the lower side.
Each is connected by screws to form a four-sided frame.

As described above, the fitting frame 4 is placed and fixed on the wall loading surface 21 of the waterproof floor 2 like the wall panel 3, but the final water return side 20 on the outer periphery of the waterproof floor of the entrance 1 is As shown in FIG. 3, the notch 2 is cut at substantially the same height as the level of the wall loading surface 21 so as to interfere with the fitting lower frame 42.
It is set to 4.

The waterproof tray 5 is provided at the lower part 4 of the fitting 1 at the entrance 1.
2 is attached to a wall loading surface 21 of a waterproof floor corresponding to a lower portion (back surface) of the waterproof floor. The waterproof tray 5 is formed of various plastics and metal materials, and has a thickness of 2 m.
m, and is attached to the fitting installation portion of the waterproof floor 2 in such a shape as to completely cover the fitting lower frame 42.

The portion of the waterproof tray 5 facing the dressing room D side is raised upward to near the level of the dressing room floor 6, and the upper end 50 of the rising portion is folded back toward the dressing room D side in parallel with the floor surface. ing.

The bathroom-side end 51 of the waterproof tray 5 is folded downward, inserted into the concave groove 22 formed in the wall stacking surface 21, and provided with a soft material 70. When the piece 7 is pushed into the concave groove 22 of the waterproof floor, it is simultaneously pushed and fixed to the floor.

Both side portions 52 of the waterproof tray are formed in a flange shape so that they can be water-tightly joined to the last water return side 20 at the outermost peripheral portion of the waterproof floor. They are connected in a watertight manner.

The waterproof floor final water return side 20 of the part where the fitting is installed, which is cut off and removed due to the interference with the fitting lower frame 42, is restored by these structures for attaching the waterproof tray 5 to this part.

The fitting frame 4 is installed in the waterproof tray 5 so as to drop both the lower frame and the lower portion of the vertical frame, and is connected to the adjacent wall panel 3 to form a unit structure. Silicon caulking 8 is applied between the washing scene 23 and the fitting lower frame 42, and a watertight connection is made between the fitting lower frame 42 and the waterproof floor 2.

The waterproof tray 5 is made of a thin material (2 m) as described above.
m or less), the rising upper end 50 of the side facing the dressing room D side can be sandwiched in the space between the fitting lower frame 42 and the dressing room floor 6, and the fitting lower frame 42 At the same time, it is connected to the dressing room floor 6 by the fitting frame mounting screws 44 without affecting the fitting dimensions. This means that the connecting flange portion 43 connecting the fitting frame 4 and the dressing room D is generally allowed to have a step of 3 mm, and most fitting lower frames are made of a plate material whose flange portion 43 is 1 mm thick. This is folded down by 3 mm, so that a thing with a thickness of 2 mm can be sandwiched inside.

A sliding door 40 is attached to the fitting frame 4.
Open and close the entrance 1 of the bathroom. The form of opening and closing is inside /
There are various variations, such as open doors that open outward, folding doors that open inside / outside, and various sliding doors.

Next, the operation of the entrance / exit floor waterproof structure of the bathroom unit will be described. The hot and cold water used in the bathroom Y is flown to the surface of the washing area 23, and most of the water is flown to a drain port (not shown) of the bathroom due to a drainage gradient formed in the washing area 23. It rushes to part 1. Conventionally, the water flowing into the entrance 1 is blocked by an entrance step formed in the entrance 1 or a drainage groove with a grating, and it is difficult for the water to reach the lower frame of the fitting. In recent bathrooms in which the steps have been reduced and drains and the like have been removed, the water used in the washing area is more likely to reach the entrance section 1. It is watertight so that it does not overflow directly to the dressing room D side.

However, the water that has been pushed to the entrance 1 is also pushed to the fitting lower frame 42 at the same time, and this part is submerged. The fitting shoji part 40 is watertight with a watertight material 9 or the like so that water does not leak directly to the dressing room D. However, the structure of the fitting frame is a butt assembly of a long extruded material as described above. For this reason, it is difficult to maintain watertightness in a submerged state if the watertightness is weak and the conditions are poor. If water leaks from the joint of the frame, the leaked water will flow to the lower part of the fitting lower frame 42 and the waterproof floor 2.
The waterproof tray 5 is caught between them and does not leak to the building frame up to the upper end 50 of the rising portion of the waterproof tray 5.

Further, since the wall loading surface 21 on which the waterproof tray 5 is installed communicates with the wall loading surface 21 around the bathroom unit, not only the water leaked from the fitting lower frame 42 but also the wall back. If water is leaked from any part of the bathroom unit, it will be caught by the waterproof tray 5.

As described above, according to the present invention, even if water is leaked from the assembled connection portion of the fitting frame 4, it can be captured by the waterproof tray 5 and the safety of the fitting portion against water leakage can be improved. it can.

Further, in this bathroom unit entrance / exit floor waterproof structure, the waterproof tray 5 of the fitting part is placed on the wall loading surface 21 of the waterproof floor 2 main body and the last water return side 20 raised on the outer peripheral portion of the wall loading surface. Since it is connected in a watertight manner, in order to reduce the entrance step, even if the last water return side 20 of the outer periphery of the waterproof floor at the fitting installation part is deleted, the water leaks to the back of the wall up to the upper end of the waterproof tray 5. Water can be stored, and the safety of the entire bathroom unit against water leakage to the outside can be increased.

For example, when water leaks from the joint of the wall panel at the corner of the bathtub far from the entrance 1 of the bathroom unit, the water leaking to the back of the wall from the seam flows to the outermost periphery of the floor. It is caught between the last water return side 20 provided and the back of the wall. Since this space communicates with the entire circumference of the bathroom unit, water will collect between the back of the wall and the final water return side 20 up to the same level, regardless of the leakage from any part. If the waterproof tray 5 is not provided and the last water return side 20 of the floor outer periphery of the fitting mounting portion is deleted, the leaking water flowing to the back surface of these walls is transmitted from the lowest level water return notch 24. It will leak out easily. In this structure, it is possible to store the leaked water up to the upper end 50 of the rising portion of the waterproof tray, and does not leak water to an external building frame or the like.

Further, in the floor waterproof structure at the entrance and exit of the bathroom unit, the side of the waterproof tray 5 facing the dressing room D side is raised up to a portion connecting the dressing room floor 6 and the fitting lower frame 42, and the connection of the fitting lower frame is performed. Since it is sandwiched and connected between the flange portion 43 and the dressing room floor 6, it is possible to store water to the same level as that of the entrance and exit fittings, and to increase the structural mounting strength of the waterproof tray 5. Can be. This means that even if the main body of the waterproof tray 5 is made of a low-strength material or a soft material, the waterproof tray 5 can have a structural strength capable of storing leaked water. This is effective for selecting the material of the waterproof tray 5 and reducing the material cost.

Regardless of the bathroom unit in any form, the effective range of the height of the last water return side 20 at the outer edge of the wall loading surface 21 is the highest up to the back surface of the connection flange 43 of the lower frame of the fitting. Rank. Because, in the fitting part, the upper end of the final water return side 20 of the floor cannot jump out of the lower frame surface, and even in the part other than the fitting part, the water return side is raised to a place higher than this height, This is because water leaks first from the gap between the back surface of the lower frame 42 of the fitting and the last water return side 20, so that it becomes substantially meaningless. That is, if the water storage level of the floor can be raised to the back surface of the connection flange portion 43 of the fitting lower frame, the water storage capacity of the bathroom unit will be the highest level in any case.

In the waterproof structure for the floor of the entrance and exit of the bathroom, the waterproof tray 5 is made of a thin material having a thickness of 2 mm or less (various plastics, metals, rubbers having no water permeability, etc.). It can be installed without greatly affecting the waterproof floor surface or the connection dimensions between the waterproof tray 5 and the dressing room D.

Also, as described above, when the rising end 50 of the waterproof tray 5 facing the dressing room D side is fixed between the connecting flange 43 of the lower frame of the fitting and the dressing room floor 6. In this way, it is possible to pinch without affecting the connection. Because of various official regulations, the entrance step is 3m
If the distance is not more than m, the thickness of the connection flange portion 43 of the lower frame is set to 3 mm in almost all fittings when viewed from the dressing room side, since it is considered that there is substantially no step. This 3 mm is not a solid 3 mm, but the end of the extruded material of 1 mm is folded down 3 mm downward, and most of the extruded material is apparently 3 mm, so there is a 2 mm hollow part in the contents, and the thickness of 2 mm If it is, it can be sandwiched in this part without affecting the fitting dimensions.

Furthermore, in the floor waterproof structure of the entrance / exit portion of the bathroom unit, a concave groove 22 is formed on the wall loading surface 21 of the portion where the waterproof tray 5 may be attached,
The end portion 51 of the waterproof tray 5 facing the wall loading surface 21 is folded downward and inserted into the groove 22, and the holding piece 7 having the soft material 70 is inserted from the upper portion into the groove 22 in advance. The waterproof tray 5 is fixed by fitting it into the concave groove 22 of the wall loading surface together with the end folded portion 51 of FIG. The strength of the waterproof tray 5 is not unnecessarily increased. This makes the waterproof tray 5
Even if the main body is made of a thin material and has a low strength or a rubber-like soft material, the main body can be securely fixed to the floor in a water-tight manner, and the labor for mounting can be reduced.
